One challenge to advancing space security is the absence of common understandings around frequently used terminology. To facilitate a shared understanding of key topics and terms, UNIDIR and SWF have developed a Lexicon for Outer Space Security.

This document aims to serve as a global reference point for terminological issues related to space security. It should be noted that the Lexicon does not intend to establish uniform definitions for all, but rather highlight, when necessary, that different stakeholders may interpret key concepts in differing ways, thus providing clarity and aiding in achieving common understanding on space security.
